A 40 GHz, broadband, highly linear amplifier, employing T-coil bandwith extension technique

Abstract

This paper presents a broadband, highly linear amplifier suitable for multi-standard mm-wave applications such as car radar, LMDS and satellite return channel. It can also be utilized as an efficient wideband output buffer, for measurements of mm-wave circuit components. It exhibits a 3-dB bandwidth of 40 GHz with a pass-band gain of 6 dB. The presented amplifier is highly linear with an IP3 of +18 dBm. It has been implemented in a bulk 90 nm CMOS LP (low power) technology and consumes 3.3 mW from a 1.2 V supply
